Giant mitochondria are a response to low oxygen pressure in cells of tobacco (Nicotiana tabacum L.)
Department of Biology, University of Antwerp UIA, Universiteitsplein 1, 2610 Wilrijk, Belgium
Abstract
Low oxygen pressure induces fast and reversible formation of giant mitochondria in cells of Nicotiana tabacum. These can have unusual shapes, attain a length of 80 µm and even form a reticulum. In contrast to animal cells, there is no such response to chemically induced oxidative stress.
Key words: GFP, giant mitochondria, Nicotiana, oxygen, respiration.
